In the Part 1 you saw the massive front of the debris flow followed by a huge wave of pouring muddy water. The elements calmed down and begann again. At the end we saw a "mud lava" flow. In this part we distingish that mud lava flow covered by furious mud water. As the "lava" has the some density as the rocks, it begins to carry them, like on a conveyor belt. Try to see two huge, huge boulders, coming over, "Gigala" at minute 3:55 and "Bigug" at minute 4:42, and a third also quite big, "Tapriunroulo" at minute 5:28 (names are given by me). The white smoke to the wall comes from the boulders and the stones which are firmly held by the "mud lava", and are crushed the one against the others.
